The nervous system is the body’s command center, a complex network of nerves, the brain, and the spinal cord that coordinates actions, sensory information, and involuntary functions like breathing and heartbeats by transmitting electrical and chemical signals. It’s divided into the Central Nervous System (CNS), comprising the brain and spinal cord for processing, and the Peripheral Nervous System (PNS), the nerves extending throughout the body for communication. Its main job is to receive information, process it, and trigger responses, controlling everything from thoughts and movement to digestion and sensing pain.
